PAINTBRUSH.

Application filed- January 5, 1922. Serial No. 527,096.

To all 'w from t may Concern/t.'

Be it known that I, Louis DAVIS, a citizen of the United States,residing at Minneapolis, in the county of Hennepin and State ofMinnesota, have invented certain new and useful Improvements in Paint-`brushes; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledinthe art to which it appertains to make and use the same.

My invention relates to what may be generally designated as paintbrushes, but which term is used in a broad enough sense to include allkinds of brushes to apply fiuids to surfaces, such for example as whatare usually designated as varnish brushes and calcimine brushes. It is awell known fact that paint brushes, except when they are very thoroughlycleaned, get hard very quickly and, moreover, when rested on theirbristles, soon get out of shape. The cleaning of a brush requiresconsiderable work and the wasteful use of turpentine or oil. Even when abrush is placed in oil, its bristles will be bent out of shape unlessthe brush is hung from its handle.

My invention provides an attachment for brushes which` will serve toenclose the bristles in a substantially airtight housing when the brushis out of use, thus making it unnecessary to clean the brush except whenit is to be put away for a very long time. lVhen the brush is in use,the attachment is not in the way but affords an extended head that maybe gripped in the hand of the user. A brush of this kind is, therefore.yvery desirable for use by painters, who have several brushes and whofrequently change brushes and carry the same from place to place. Insuch use of the brushes, the brushes, when out of use, are simplyenclosed in the housing and set aside where they will be properlyprotected and properly held in shape until again used. These housingsalso permit the brushes, without cleaning, to be placed in a carryingease and carried from place to place. 0f course, these brushes do notneed to be placed in oil to keep the same from hardening nor, of course,when the brush is to be placed away for a long time, in which case thebrush can be cleaned, but even then the housing will hold the same inshape.

In the accompanying drawings, which illustrate the invention, likecharacters indicate like parts throughout the several views.

Referring to the drawings:

Fig. 1 is a perspective showing the brush designed in. accordance withmy invention and adjusted for use;

Fig. 2 is a perspective showing the brush.l

with its housing closed;

Fig. 3 is a View showing the housing opened up and in a positionyintermediate or between the positions shown in Figs. 1 and 2; and fFig. 4 is a fragmentary section'taken on the line 4-4 of Fig. 3.

The brush comprises the usual bristles 5 set into a headV 6, whiehlatteris preferably made quite narrow longitudinally of the brush. The brushhandle 7 is provided with a cap 8 of substantially the same generaloutline as the head 6. To the opposite sides of the handle cap 8, sheetmetal housing plates 9 are hinged atlO. These housing plates 9 are madeto fit quite closely against the sides of the bristles 5, and they areprovided with overlapping closely engaging side flanges 11. vWhen thecap 8 is pressed against the head 6 and the housing plates are closedagainst the bristles, the free edges of said plates will come togetherand the side anges 11 will completely close the sides of the housing,thus enclosing the lbristles within a substantially air-tight housingand holding the bristles in perfect form.

To the central portion of the brush head 6 is rigidly secured a longstem or bar 12 that works freely through a longitudinal passage formedin the handle 7 and lextended centrally through the cap 8. This stem'12, therefore, guides the handle 7 and cap 8 for sliding movementstoward and from the brush head 6.

For automatically opening and closing the housing plates 9, wire links13 are pivotally connected thereto andto the brush head 6. Preferably,these links 13 are arranged in pairs, the members of the pairsbeing par*allel. l v

The handle 7 is shown as provided with a hollow sheet metal cap 14provided within the spring-actingdog or detent 15 that is engageablewith notches or teeth 16 formed on one edge of the stem-12. Said stem 12works treely through the slot in the outer end of the cap 14C and ispreferably formed at its outer end with a knob or head 17.

When the handle and parts connected thereto are slid on the stein l2toward the vbrush head 6, from the position shown in Fie'. l, thehousing plate 9, by the linlzs 13, will iirst be opened up, as shown inFig. 3, and will then be closed against the bristles, as shown in Fig.Nhen said handle and parts connected thereto are slid outward trein theposition shown in Fig. 2, said housing; plates `will again be opened up,as shown in Fig'. 3, and will then be closed together or against thebrush head G, as shown in Fig. l. The engagement ofthe springacting` dogor detent l vwith the teeth on the stem l2 serves to hold the handle onthe stem in Whatever position it may be set. Hence, when the housing,`plates are closed as shown in Fig. i?, they Will he held in such closedpositions, and when adjusted as shown in l, theT will be held againstthe brush head thereby affording a long` extension to the brush headalwhich is adapted to be Very iirinly gripped in the hand While the brushis being used.

The device described may be applied to brushes at comparatively smallcost, and Will be found eiiicient for all of the purposes had in View.Moreover. it Will increase the life oic the brush and always keep thesame in goed form and ready for use.

Vhat l claim is:

l. The combination with a brush head having` a projecting stein, of ahandle slidable on said stein, and housing plates hinged to said handleand adapted to enclose the bristles when said handle is slid toward thebrush head. y

2. The combination with a brush head having' a projecting stein, of ahandle slidable on said stem, and housing plates hinged to said handleand adapted to enclose the bristles When said handle is slid toward thebrush head, said housing plates being` securable against the brush headWhen said handle is slid on said stem away from the brush head.

8. The construction defined in Claim l in further combination With akspring-acting dog on the brush handle engageable With notches on saidstern for the purpose described.

4f. rlhe combination With brush head havinga projectingstem, of a handleslidable on said stein, housing plates hinged to said handle and adaptedto enclose the bristies when said handle is slid toward the brush head,linlrs pivotally attached to said housing` plates and to the brush head,and

spring-acting dog on the brush handle engageable with notches on saidstem to hold said handle against sliding' movements .in one position inwhich said housing plates enclose the brush and in another position inwhich said housing plates are held closed against the brush head.

ln testimony whereof l affix my signature.
